tors, of which the followingis a specifica tion.

This invention relates to cable winding drums, and more especially to those em ployed on a wheeled carrier such as an automobile and connected withpower mechanism whereby the drum may be rotated to draw on a rope or chain and extract the vehicl from a rut or mud holein which it has become stuck or stalled.

The primary object of the invention is to connect the drum with the front end of the crank shaft at the point where theengine is cranked, so that when the engine is started up the extractor mechanism will be operated without the necessity of throwing in the clutch and putting strain on the latter. Y

Another object isto avoid the use of any kind of clutch mechanism which would increase the parts and therefore the weight and expense of the sundry, because my invention is to be considered an attachment which is to be carried in the tool box and applied only when it is necessary for it to be used-therefore it comes under the head of motor vehicle sundries or accessories.

Other objects will appear from the following specification and claims, reference being had to the accompanying drawings Wherein:

Figure 1 is a plan view of the front end of a motor vehicle'with this attachment in place,

gig. 2 is a front elevation of the same, an r Fig. 3 is a central longitudinal section, the chain or yoke and the block and tackle being omitted from Figs. 2 and 3.

gig-.4 is a detail of the connecting shaft, an

Fig. 5 is a detail of the driving crank referred to herein aftergwlriie Fig. 6 is a detail of one means for attaching the device to the frame.

In the drawings th letters W designate the front wheels of a .motor vehicle, mounted onan' axle A which underlies the springs S suitably connected to the frame bars F as usual. The latter support the engine whose main shaft M has a coupling C at its front end to receive the cranking handle when the engine is to be started; and R designates the radiator beneath which this handle is passed for this purpose. No novelty is claimed fOr the parts thus far described.

Coming now to the details of the present invention, the numeral 1 designates a steel rod or shaft detachably connected at its extremities by suitable means such as clips 2 to the frame bars F, and 3 is a yoke which by preference is a section of chain also detachably connected with said frame bars, possibly by means of the same clips as indicated in Fig. 6. Connected with the center of this yoke is a block-and-tackleniechanism l whose forward pulley block has a section of chain 5 capable of attachment at 6 to a stake driven in the ground or a tree or a fence post, or some object forward of the automobile or motor vehicle which we will understand is stuck in a rut or mud-hole in on the rod or shaft 1 between suitable thrust bearings 11 and carrying atone end a ring gear 12 which is in constant mesh with a driving pinion 13. The latter is fast on a short shaft section 14 connected by a universal joint 15 with another shaft 16 which is squared as shown at 17. Engaging the squared portion-is a socket 18 of similar shape within a third shaft section 19 -'the whole making up a driving sha ft as best seen in Fig.- 4E. The rear end of the driving shaftis supported in the coupling 0 in a manner yet to be decribed, and its front portion is support ed by a bearing 9 inclosingthe front section 14, the bearing being carried at the center My H shaft is turned in the proper direction, motion is transmitted to the drum and the rope 7 is wound thereon; and it is obvious that when tension is imparted to the rope, the block-and-tackle mechanism will cause the automobile or motor vehicle to be drawn out of the position where it is stalled. The primary object of the present-invention is to rotate said drivinpj'shaft, from the forward or cranking end of themain shaft M of the motor vehicle instcat of through its clutch mechanism or by any attachment which is indirectly connected with said main shaft as formerly. 4

I have employed the letter C to designate the coupling at the front end of the main shaft, into which the usual crank handle is inserted when the engine is to be started. I do not wish to be limited to the construction of this coupling, and in fact my attachment is usually applied to motor vehicles which have a self-starter. But 1 prefer that the rcarmost shaft section 19 as shown in Fig. 4 shall be provided with pins 20 or other means by which it can be connected with the coupling C when the attachment is put inplace, and in order to hold it so connected I prefer to insertan expansive spring 21 within the socket 18 so as to normally distend the shaft section 17 as will be clear. However, when the attachment is removed, or at times when it is not in use at all, the crank shown in Fig. 5 can be employed for starting the engine. 4 This crank is of ordinary construction excepting that its rear extremity 28 should be squared to fit the square socket 18. The interior of this socket while spoken of as being square, could of course have other angular configurations, and when the shaft section 17 is withdrawn and removed the squared extremity of the crank can readily be inserted therein as will be clearly understood. ()r it might be possible to remove the shaft section 19 along with the other sections of the driving shaft of this attachment, and shape the rear extremity of the crank t0 lit the coupling C as usual, but in that case the rear end of the shaft section 19 should be shaped to fit such coupling the same as does the crank handle.

Whcn not in use this attachment is stored in the tool bOX or at some convenient place within the body of the motor vehicle. 'VVhen the latter becomes stalled in the roadway or elsewhere, the drivertakesthe attaclnnent out of the tool box, and by means of the clips 2 fastens it to the frame bars F, conmeets the yoke and block-and-tackle mechanism, and leads the chain forward and at taches it to some permanent object at 6, while the rope 7 is left quite free but its rear 4 end is brought back to and wound around and attached to the drum 10. The telescopic shaft sections 17 and 1,9 are now engaged tackle features, and

with each other and the rear tnd of the sec tion 19 with the and the rope 7 is wound thereon. The oper ator guides this rope in proper coils around the drum, and very soon itbecomes taut; after which continued operation of the drum puts tension on the entire attachment and the motor vehicle is" drawn out of place. The engine is then immediately stopped, the attachment disconnected and laid away, and the driver proceeds on his way. Attention is invited to the point previously made in this specification, which is that the driving shaft connecting does not lead through the clutch mechanism or through any devices or means indirectly the drum with the engine connected with the main shaft M. The use of the universal joint 15 isonly to cause the.

forward shaft section to be deflected a little, as usually are-the front ends of the frame bars F, and it is necessary whenthe clips 2 are attached to said framev bars near their front ends and in order to give room between the n'i-ain shaft 1 and the coupling 0 for the interposition of the-driving shaft shown in Fig. 4. The telescopic connection between the shaft sections 17 and 19 is necessary to permit the insertion of the device after the main shaft 1 hasbcen attached to the frame bars, and the detachable coimcc tion of the shaft section 19 with the coupling O is necessary in order that when it is not employed the crank handle of'Fig. 5 K

may be used. The parts are preferably entirely of metal excepting the block-andfurther details need not be amplified.

What is claimed as new is 1. In an automobile extractor, the combination with a rope. a winding drum therefor, a rod on which the drum is rotatably mounted, detachable connections between said rod and the frame bars of the motor vehicle, and an arch whose ends embrace said rod and whose center has a bearing; of'a beveled gear on said drum, a driving shaft mounted near its front end in said bearing and having a pinion engaging said gear, its body being in three sections, a universal joint between two of said sections,

a telescopic connection between two other said sections, means for normally distending these sections, and means for detachably connecting the rearmost section with the main shaft of the engine of the motor vehicle.

2. In an automobile extractor, the combination with a rope, a winding drum therefor, a rod on which the drum is rotatably mounted, detachable connections between said rod and the frame bars of the motor vehicle, and an arch whose ends embrace section abutting against the end of the front said rod and Whose center has a bearing; of section, and means at the rear end of the a beveled driving gear on said drum, a rear section for detachably connecting it 10 driving shaft made in telescopic, sections; with the coupling at the front end of the end having one section mounted in said main shaft of the motor vehicle engine.
